COTTON-TH'INNING PLOW.

Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed July 18,1906. Serial No. 3263113.

To all whom it may concern.-

Be it known that 1, WILLIAM ALAXANDER EDGIN, a citizen of the UnitedStates, residing at Graford, in the county of Palo Pinto and State ofTexas, have invented a new and useful Cotton-Thinning Plow, of which thefollowing is a specification.

This invention has relation to cotton-thinning plows; and it consists inthe novel construction and arrangement of its parts, as hereinaftershown and described.

The object of the invention is to provide a plow adapted to be drawnacross the fields of cotton in directions transverse to those in whichthe rows of cotton extend. The plows are spaced apart, and such plantsas pass between such space remain, while'those that are engaged by theblades of the plow are cut and destroyed. In advance of each plowpointis a colter-wheel. spaced apart correspondingly to the spacing betweenthe said plows. The said wheels are adapted to cut into the earth, andthereby afford an incision which is followed by the plows, andconsequently the earth bearing the roots of the plant intended to bepreserved is not unnecessarily distributed or agitated.

In the accompanying drawings, Figure 1 is a perspective View of theplow. Fig. 2 is a vertical sectional view of the colter-wheels carriedby the plow. I

The plow consists of the beam 1, to the rear end of which is bolted theplow-standards 2 2. The said standards at their lower portions are bowedoutwardly, as at 3, and at the lower ends of said portions 8 are locatedthe cutting-blades 4 4. Said blades are pointed at their-forward endsand areprovided with substantially horizontally forward cutting edges.The said cutting edges are adapted to engage the roots of the plants andsever and destroy the same.

The colter-standards 5 are clamped to the beam 1 by means of theU-shaped clampbolt 6. The said standards 5 are also provided at theirlower ends with the bowed portions 7 7. The sleeve 8 is transversely supported at the lower ends of the standards 5 5 and is retained inposition upon the ends thereof by means of the bolt 9, which is securedat its ends to the lower ends of the said The said wheels are standards5 5. The sleeve is j ournaled upon the bolt 9. The colter-wheels 1O 10are fixed to the sleeve 8. The said wheels 10 10 are spaced apart, andone wheel 10 is located directly in advance of the point of the blade4'that is to say, lines drawn from the point of a blade through thevertical axis of the colter-wheel in front of the same are parallel to aline similarly drawn from the opposite blade to the oppositecolter-wheel.

From the foregoing description it is obvious that as the implement isdrawn over the field of cotton in a direction transverse to that inwhich the rows of plants extend the blades 4 will cut the roots of theplants at intervals as they pass across the rows of cotton and that suchplants as occur in the row between the pointed ends of the said blades 44 are not disturbed. The colter wheels 10 traveling in advance of thesaid blades cut incisions in the soil and also sever in a verticaldirection the roots of the plants, so that the said roots are not pulledlaterally by the blades 4, and consequently the earth about the rootsintended to be preserved is not unnecessarily agitated or disturbed.

Having described my invention, what I claim as new, and desire to secureby Letters Patent of the United States, is-

1. A cotton-thinning plow consisting of a beam, standards attached tosaid beam and having their lower ends spaced apart, cutting bladesattached to said standards, colterstandards attached to the beam inadvance of the blade-standards, a bolt connecting said colter standardstogether, a sleeve journaled upon said bolt, and colter-wheels fixed tosaid sleeve.

2. A cotton-thinning plow consisting of a beam, standards attached tosaid beams and having their lower ends spaced apart, cuttingbladesattached to said standards, colterstandards attached to the beam inadvance of the blade-standards, a bolt connecting said colter standardstogether, a sleeve journaled upon said bolt and bearing at its endsagainst the colter-standards and colterwheels fixed to said sleeve.

3. A cotton-thinning plow consisting of a beam, standards attached tosaid beam and having their lower ends spaced apart, cuttingbladesattached to said standards, colterstandards attached to the beam inadvance In testimony that I claim the foregoing as of theblade-standards, a bolt connecting my own Ihave hereto affiXed mysignature in said colter standards together, a sleeve the presence oftwo Witnesses.
